Triumph Street Triple powers Moto2

Triumph Street Triple powers Moto2

Triumph Motorcycles has signed a deal with Dorna to power the Moto2 class from 2019 with Street Triple engines making 95.5kW instead of 90kW in the Street triple RS version.

Honda has powered the MotoGP feeder category with its 600cc engine since it began in 2010 when it replaced the 250cc two-stroke class.

Now Triumph will be the engine supplier with a race-tuned version of the triple-cylinder donk out of the Street Triple.

That means an increase in capacity for the class to 765cc.

It may also mean some race-tuned Street Triple versions coming out of the factory.

Triumph has signed a three-year deal with Dorna, the commercial rights holder of the MotoGP series.

As part of the development of the engines, they are expected to be used in the CEV Moto2 European Championships from next year.

Here is a video of the engine undergoing dyno testing.

Triumph Daytona 675R engines have powered super sports wins at the Isle of Man TT, Daytona 200 and British Supersports Championships in 2014 and 2015.

But the new engine is a significant upgrade.

The Daytona-derived 765cc Street Triple engine has more than 80 new parts including an increased bore and stroke, new crank, pistons and Nikasil-plated aluminium barrels.Triumph Street Triple powers Moto2

The flagship RS has 90kW of power at 11,700rpm, up 16%, and 13% more torque at 77Nm @ 10,800rpm.

The Moto2 engine will come with an ECU developed by the supplier of MotoGP’s control unit Magneti Marelli.

Triumph chief commercial officer Paul Stroud said: “This is a significant moment for Triumph that brings an exciting new chapter to our 110-year racing history and builds on our celebrated TT and Supersport race winning triple engines.”
